On the deleted scene:
Personally, I think that "Goodbye Love" and, since it's also a deleted scene on the DVD, "Halloween," are rather important in the story. Roger and Mark's fight is especially important for character development. I can see why they decided to leave both out of the movie because I suppose they could've slowed down the ending, but I still think they should've been left in the movie.
Anyway, onto the actual scene...The fact that this scene takes place in the apartment rather than outside the church fits the movie very well (before I get attacked, I said it fits the MOVIE). I think it adds to the emotional "turmoil," if you will, of the movie. Although it was short, I think that the scene was pretty good...I found myself wanting to shout after Roger's car, but of course, that was due to my complete insanity, not the scene.
